<p>PROBLEM TO BE SOLVED: To provide a new vibration damping structure for a trolley wire that lowers the cost of a damper itself and facilitates a mounting work thereof at a low cost, and has a high vibration damping effect. SOLUTION: For damping a trolley wire, a suspension wire 10 for holding the trolley wire suspended is mounted with the damper 18 having a rigid holder 20, an impact mass 22 arranged floatingly at right angles to the axis on a tubular part 26 of the holder 20 so as to impact the tubular part 26 at vibration, a clearance S for permitting the impact mass 22 to move floatingly at right angles to the axis, and a layer of a rubber elastic body 34 formed on an inner circumference of the impact mass 22.</p> |
